SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 399,462, dated IEIareh 12, 1889.

Application filed August 3, 1888. Serial No. 281,912. (No model.)

To aZZ whom it may concern.-

ie it known that 1, JOHN IIARTZELL ZINN, of Gettysburg, in the county of Adams and State of Pennsylvania, have invented certain new and useful Improvements in Sulky-Plows, of which the following is a specification. I

This lllTGl'ltlOl]. contemplates certain improvements in sulky or gang plows; and it consists of the sundry combinations of parts, includin their construction, substantially as hereinafter set forth, and pointed out. in the claims.

In the accompanying drawings, Figure 1 a plan view of my inventiol'l with parts broken away. Fig. 2 is a side elevation, also with parts broken away; and Fig. 3 a transverse sectional View of. the same, which section is taken in rear of the plow and looking forward. Fig.1 is an enlarged detail view thereof, showing one ofthe plowbeams, including the means for suspending or securing it in positiou, also its plow and the plow-connecting clip or socket. Fig. 5 is also ancnlarged detail view thereof, partly in section and elevation, showing more fully the sliding-seat connection and the roller-tongue or pole connection, including certain other parts. Fig. (i is a detail view.

In the embodiment of my invention I provide a suitable frame, A, preferably of the construction shown, the same having front and rear and side pieces, and intermediate parallel pieces, a (1, connecting with the front and rear pieces.

Applied to the frame A are two slotted crosspieces, Z) Z), being confined thereto by staples or keepers b b, one fitted in a socket, N, at the outside of each side piece and atthe inner side of each intermediate piece, a. The cross-pieces b I) rest at their inner ends upon a slotted connecting-piece, l), which is held firmly against said cross-pieces by the staples or keepers securing in position those ends of said cross-pieees B B are beams, which are horizontal the greater portions of their lengths, but are curved upward at their ftn'ward ends and provided thereat, upon the sides, with plates 0 c, projecting and forming sockets or clips beyond said ends of lhebeams, which receive and are pivoted to pendants or posts 0 0, s1 rung along the slotted cross-pieces 717). This arrangement effects the articulation of the beams B B, so as to permit of the adjustment or raising and lowering of the same, as is required in working the plows. The upper ends of the pendants or posts c c are formed with tenon-like screw-threaded projections c which are held by nuts in the slots of the cross-pieces b I), while the beams B B are connected together by slotted cross-pieces or yokes d d, which receive screw-bolts d d, entering the beams, whereby the beams are adapted to be adj ustcd at the required interval apart and held parallel to each other.

The rear ends of the beams l B are provided with clips or sockets c 6, each of which is preferably formed of a single casting, with its lower or bottom portion arranged upon and disposed a short. distance from the under side of the beam, while its side portions are applied and held by screw-bolts to the sides of the beam. To one of the socket or clip curing bolts of the outside one of each series of beams (of which two are here shown) is applied. an eyebolt, j", which reaches up and is uutted to the cross-pieces or yokes (Z (Z, to

effect the holding of the assembled beams of the series bodily together.

C are the plows or shovels, preferably of the form shown, which are adapted to connect with the sockets or clips (2 (a, the upper ends of their shanks being inserted and removably held in. said sockets by set or holding screws e c.

D is a shaft journaled or hung in bearings or boxes applied to the intermediate and side pieces of the frame A, and to which shaft is fitted a beveled gearavheel, y], with which intergears a small beveled pinion, g, secured to the lower end of an upright shaft, 71, to the upper end of which is applied a hand wheel or lever, h, for its convenientmanipulation by the driver or attendant. A suitable pawland-ratchet mechanism in practice is applied to the machine to prevent the gearing against movement under the weight of the plowbeams when elevated. The shaft D is provided with arms d (P, which are adjustably connected by adjusting screw bolts or pins, and apertures in the arms with stirrups or bails D D, through eyes in the upper ends of the arms of which. are passed said screws, and which take or [it under and in gains or ICC notches (Z in the under side of the beams B. Two or more notches or gains (Z (Z are supplied to each beam B to effect an adj ustable connection between the bails or stirrups I) D and said beams. It will be seen that by properly manipulating the hand or lever wheel 7L the gearing g g, with the shaft D, will be revolved, which will effect the re quired movement of the arms (Z (Z which in turn will operate the bails or stirrups D D, effecting the lifting or lowering of the beams B with their plows or shovels, according to the direction in which the hand or lever wheel is turned. I

Hung in rear of the plows or shovels is a roller, E, preferably of the construction shown, and having connection with the frame A. This connection is effected by means of a plate, 2', bolted to the pole or ton ue of the roller and deflected or inclined downward and forward from a horizontal line, and provided, it may be, as in the present instance, with a removable wooden pin or plug, 1', which enters an apertured step-like plate, j, bolted to and extending rearward and downward from the under side of the intermediate pieces, a a, of the frame A. This secures a swiveling connection between the roller tongue or pole and the carrying-frame just referred to, to enable the roller to readily accommodate itself to the line of travel of the machine or plows.

The rear part of the frame Ais mounted or carried upon rimmed spoked wheels F, which are borne by short axles or shafts F, whose spindles or vertical portions F extend up through bearings or eyes 7t 70, secured to the sides of the frame A. Upon said spindles, below said bearings or eyes, are applied nuts k, bearing against the latter and limiting or properly disposing the spindles therein.

7c? are bracing collars or sleeves, up through which also pass the spindles or vertical portions I of the axles or shafts F, which collars or sleeves are connected by rods or arms to the under side of the rear end of frame A. Fitted upon the spindles or vertical portions F of the axles F, near their extreme upper ends, so as to turn or actuate the same, are short plate-like levers Z Z, which are held upon said spindles against upward displacement by nuts Z Z, screwed upon said spindles. These short plate-like levers Z Zare connected by means of a link or bar, G, to which is connected and which is actuated by means of a hand-lever, H, pivoted or fulcrumed upon a conveniently-disposed bar or support, 011, secured to the frame A. By the movement of the handlever Hin the required direction the connecting bar or link G is so acted upon as to effect the movement of the levers Z Z, which in turn actuate or turn the spindles F with the axles F and wheels F, whereby the line of travel of the machine can be changed at pleasure and the guiding of the same be effected according to the direction in which it is desired the machine shall move.

I is a slotted plate-like lever, which is pivoted at its forward end to a cross-piece secured upon the parallel pieces a a of the frame A, while in its slot works a headed pro ection or screw, 02, projecting upward from the link or bar G, thereby eifeetin g a connection between said lever I and link or bar G. The lever I has applied to its upper side apawl or detent, t which is adapted to engage with a notched segment or rack, i secured to the sides of the parallel pieces a a and bridging over .the forward pivoted end of the lever I. Thispawl or detent 1' slides in an open-ended closure or tube, i which consists, preferably, of two plates, each forming a semi-tube, and having their meeting portions extended into flanges or wings placed parallel and in contact with each other, and bolted or screwed together and to the upper surface of the lever I, the

lower semi or half tube of said closure or tube resting in the forward portion of the slot of said lever. The pawl or detent Z is actuated by a supplementary or cranked lever, I, linked thereto and fulcrumed upon the lever I, whlch supplementary lever also serves as a convenient means for the manipulation of the lever I, the levers requiring successive actuation. The pawl or detent, as is obvious, is to effect the retention of the lever I at its required point of adjustment.

J is the drivers seat, which is secured or mounted upon a proximate bail-like stepped spring or support, j, the seat being applied to the upper step or horizontal portion thereof, while the arms of the lower horizontal portion thereof are passed through and supported in staples or keepers 7' j applied to the sides of the parallel pieces a a of the frame at its rear end. This arrangement permits of the adjustment of the seat either forward, balancing the tongue as is desired when the machine is on the road, or rearward to partly take the weight off the horsesorteams neck when the plows are at work.

K is the draft pole or tongue, which is provided with arms K, formed of plates with their forward ends bolted or fastened to the sides of the tongue or pole near its rear end, and extended laterally outwardly and then rear\\'*ardly. The rearward extended portions of the arms K are strengthened or braced by a clip-like plate, K fastened to the tongue or pole, which arms are provided with series of apertures to receive the securingbolts for its attachment to the frame A.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with the carryingframe having the longitudinally-slotted bar applied thereto, of the pendants or posts having tenon-like projections fitting in the slotof said bar and provided with screws fitted with nuts, and the plow-beams provided at their inner ends with. socket-forming plates articulated or pivoted to said pendants or posts, substantially set forth.

2. The combination, with the plow-beams and the plows, of the clips secured to said beams at their outer or rear ends, the slotted cross-bars connecting said beams, and adjusting-screws to effect the holding of both the shanks of the plows and the crossbars, substantially as specified.

The combination, with the carryingirame, of the plow-beams applied thereto, the slotted bar or yoke (Z, adjustably securing said beams, the sockets or clips 6, holding the plow-shanks, and eyebolts f, receiving bolts from said beams and connecting with said slotted bars or yokes (Z, substantially as and for the purpose described.

4. The con'lbination, with the carryingframe provided with plows, of the roller having its tongue or pole provided with a deflected or angled plate having a pin or stud engaging with an apertured si-eplike plate applied to the carrying-frame, substantially as set forth.

5. The. combination, with the carrying frame, of the wheels borne by axles having spindles applied to said frame and provided with levers connected or linked together, a handle\'er for actuating the link or connecting medium between the aforesaid levers, the pawl or detent engaging with a ratchet positioned upon the carrying-frame, which pawl or detcnt is disposed to move edgewise in a guide or clip secured upon parallel bars or pieces of the frame, and which pawl or detent is actuated by a crank-lever linked thereto, substantially as set forth.
